nobody can finish 200m in 90 seconds. it is the new world record!
Actually, if you can finish 100m in 90 seconds, your skills are
almost perfect. swimming is not like running, there are big
difference in the speed if your skill is not perfect. If you
don't have special training, you cannot swim well. For example,
normal person can run 1000 meter in 4 minutes, but normal person
cannot finish 100 meter in free style swim. 2000 meters is
mission impossible to normal person, but it is just a piece of
cake for professionals. probably a man with skill can keep swiming
for 4-5 hours until he feels hungry and never feel tied.
